Aquaculture Research, Volume 2025, Issue 1, 2025.Monogeneans are ectoparasites that in high densities, can cause harm and even death to their hosts. Therefore, treatment methods are continuously evaluated. The current study aims to determine the LC50 of ionic silver and silver‐engineered nanomaterials (ENMs) (nAg) in the monogenean Macrogyrodactylus congolensis and report on the toxicological effects

Diversity and host specificity of monogeneans in Antarctic fishes: a review
Український антарктичний журналWe compiled and harmonised published records of monogeneans from Antarctic and sub-Antarctic fishes, standardising host names, georeferencing localities, deduplicating records, and excluding ambiguous entries (genuslevel hosts or “not specified” hosts ...

Aquaculture Research, Volume 2025, Issue 1, 2025.The increase in fish production in aquaculture reflects the growth of the world population. However, this expansion is accompanied by challenges, such as the intensification of production systems through increased stocking density, which induces stress in fish, weakening their immune system and making them more susceptible to disease outbreaks ...

Journal of Fish Biology, Volume 105, Issue 6, Page 1501-1539, December 2024.Abstract Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas ...

Amino acids ofDiclidophora merlangi(Monogenea)
Parasitology, 1975 The level of free amino acids inDiclidophora merlangiis high, comprising over 500 μmoles/g ethanol extracted dry weight. A single amino acid, proline, constitutes some 70% of the total pool. Analysis of parasite protein and host blood and mucus revealed low proline levels, suggesting that the high free pool content was not related to a requirement for ...

Oxygen uptake byDiclidophora merlangi(Monogenea)
Parasitology, 1974 Diclidophora merlangiwas found to consume oxygen under a variety of experimental conditions. TheQo2of homogenates was 0.415 μl oxygen consumed/mg wet wt/h. Oxygen uptake was reduced in the presence of inhibitors: cyanide 0.1 mM and 5.0 mM, 100%; rotenone 10−6M, 56%; antimycin A10−6M, 63 %; malonate 10 mM, 36 %; arsenite 5 mM, 46 %; fluoroacetate 5 mM ...
